Tow Bar Fix

I had trouble with my tow bar squashing its own tube when the forks were inadvertently forced together during handling. This prevented the handle from retracting into the body. I put a 7 in. length of 5/16 in. diameter aluminum rod inside the spring to act as a stop. Problem solved. I think a wooden dowel or even a pencil might work, at least for a while. See the attached picture. --Frank
